2016 15 inch Critical Update Error

[MOMOH]

Have got a 2016 MacBook Pro Touch Bar with the following error and would not go past it 'A critical software update is required for your Mac. connect to a Network to install this update, your Mac can't be used until this update is installed.
I have tried to install the update but always fails with the same error. I look out the board and installed it into a different housing to rule out the Touch Bar as the issue , but no changes.. where do I go from here guys

Nothing new apart of already posted.
Did you try all mentioned there.
Looks like a driver for touchbar must be downloaded...
